How to frame a header for a sliding glass door.

Between 4 and 5 feet the header should be built 2 inches wide and 8 inches long while a larger opening needs a header that is 2 by 12. To make the door header the top of the door frame cut two 2x4s to the same length as the width of the original opening and nail them securely together. When in doubt build a double 2 12 header sandwich like we explain next. Most door frames that are 4 feet wide or less require a 2 by 6 header.

Non load bearing windows and doors do not require a structural header. Also be aware double or triple jack studs may be required based on the opening width and the load the header carries. Cut the door header. In all but the most bizarre situations they ll easily carry the weight for 4 ft.

Be sure to check code requirements prior to framing. A 36 door has a rough opening width of 38 so your header is cut at 41. The steps to frame a sliding door and the tools required for the job are listed below. You will need to add 1 2 of plywood between the 2x4 s to get the right wall thickness of 3 1 2.

For instance in the basement remodel all the doors have simple 2 4 framing around them. If the door is not framed correctly the door will not stay in place. This is the actual thickness of a 2x4. Section r502 5 shares allowable girder and header spans.

When in doubt use 2 by 12 inch headers. Measure the width of your door frame.
